IMPROVEMENT IN SAW-TEETH.

Specification forming part of Letters Patent N0. 162,061, dated April 13, 1875; application tiled February 12, 1875.

To au whom it may concern:

Be it known that I, IVM. P. HALE, ot' Port Huron, in the county of St. Clair and State of Michigan, have invented. certain new and useful Improvements in Saw-Teeth; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon, which form part of this specification.

My invention relates to what are known as inserted teeth for circular saws; and it consists in the construction of a saw-tooth with a projecting tlan ge on both sides along the front or cutting edge, and with miter corners in the saw.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing. in which- Figure l is a side View of a part of the sawblade, with my improved sawtooth inserted therein. Fig. 2 is a perspective view of the saw-tooth.

A represents the saw-tooth, provided with a groove, a, along both its frontpand rear edges.

The point B of the tooth is formed with a projeciing flange, b, on both sides of the front or cutting edge, for the purpose of clearing the kert'. The face of the point B may be hat or concave, as desired. The inner end or heel of the tooth is formed with miter corners d d, for the purpose of preventing the saw from cracklng.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The insertable saw-tooth A B, provided with grooves a, a, projecting flanges b b along the front or cutting edge, and miter corners d d at the heel, constructed substantially as shown and described, as and for the purpose set forth.

In testimony that I claim the foregoing as my own I atiixmy signature in presence ot' two witnesses.
